Gold nanoparticle patterning by self-assembly and transfer for LSPR based sensing

We successfully demonstrated a pattern formation of 60 nm gold nanoparticles using high productive combined technique of particle self-assembly and the assembled particle pattern transfer, and its availability for bio/chemical sensor with localized surface plasmon resonance (LSPR) of the patterned particles was verified. Dot and line patterns of nanoparticles were fabricated on a flexible PDMS substrate by proposed method. In addition, by measuring spectrums of assembled nanoparticle arrays, it was confirmed that the LSPR optical characteristic can be controlled by patterns of the assembled nanoparticles.
